When using RAG in Prompt Studio, an error occurs.

[takk]

Hello, I'm trying to build a RAG (Retrieval-Augmented Generation) model following the knowledge provided below, and I'm attempting to run tests on the extended LLM (Language Model) using Prompt Studio. However, when running it in Prompt Studio, I encounter an error. The error message is as follows. Could you please advise?

Hello,

This comes from a breaking change in langchain-community 0.0.27. This will be fixed in an upcoming DSS release.

In the meantime, you can limit the version of langchain-community to <0.0.26 in the code environment you use for RAG:

langchain-community<0.0.27

 and rebuild the code env, this should fix the issue.

Hello,

As a followup, this was also fixed in Dataiku DSS 12.6.0.
